摘要
传统防雷方法可以分为阻塞式、疏导式和疏导灭弧式三种,本文在总结性分析传统防雷方法优缺点的同时,介绍了"疏导—灭弧—阻塞"式创新性防雷方法,主要从其防雷机理、特点、安装维护和防雷效果几个方面展开论述。结果表明,"疏导—灭弧—阻塞"式防雷方法拥有巨大的优越性,能在继电保护动作之前,强力阻断工频续流电弧,防止雷击跳闸事故的发生,能大幅度提高输配电线路供电可靠性。
The traditional lightning protection methods can be divided into three types: blocking type,guiding type and arc extinguishing type. The advantages and disadvantages of traditional lightning protection methods are analyzed,and the innovative lightning protection method of "guiding-arc extinguishing-blocking"is introduced. The author mainly discusses its lightning protection mechanism,characteristics,installation and maintenance as well as lightning protection effect. Results show that the method of"guiding-arc extinguishing-blocking"has great advantages,which can strongly block the power frequency continuous current arc before the relay protection action,so as to prevent lightning trip and greatly improve the power supply reliability of transmission and distribution lines.
